CHARLES WALLACE HUNT, OF WEST NEW BRIGHTON, NEW YORK.

DUMPING-BUCKET.

To all whom it may concern:

Be it known that I, CHARLES ,VALLAon HUNT, a citizen of the UnitedStates, residing in Vest New Brighton, in the borough of Richmond of thecity of New York, in the State of New York, have invented certain newand useful Improvements in Dumping-Buckets, of which the following is aspecification, reference being had to the accompanying drawings, forminga part hereof.

This invention has for its object the production of an improved bucketfor hoisting and handling coal, ore or other materials, which can bevery easily dumped by hand through the bottom, the gates or jaws whichform the-bottom of the bucket being so mounted and provided with suchlocking and operating means that when in closed position they supportthe load without danger of accidental discharge and yet can be openedwith little effort.

The invention will be more fully explained hereinafter with reference tothe accompanying drawings in which it is illustrated and in which Figure1 is a View in side elevation of a bucket which embodies the invention,the bucket being closed. Fig. 2 is a view thereof in side elevation.Fig. 3 is a view similar to Fig. 1 but showing the bucket open. Fig. 4is a view in section on the plane indicated by the broken line t-t ofFig. 3.

The body or shell a of the bucket may be made of any suitable materialand may have any suitable form and dimensions. As shown, it is asubstantially square body, without top or bottom, and is provided with asuitable bail b. The bottom of the bucket is formed by two jaws or gates0, c, which, when closed, support the load, and when open, as shown inFig. 3, permit the load to be discharged between them. Each jaw or gateis carried by arms or cheek pieces (Z which are pivoted upon studs 6mounted in the opposite side walls of the bucket. The pivotal axis isnearly equi-distant from the inner and outer edges of the aw, so thatthe jaw is nearly balanced, the pivotal axis be ing preferably a littlenearer the vertical plane of the outer edge so that the slightlyunbalanced load on the jaw assists in the opening of the jaw when itsopening movement is started. The two opposed cheek pieces cZ, (Z, ateach side of the bucket, are 1 connected by a link j which is pivoted toSpecification of Letters Patent.

Patented Aug. 23, 1910. Serial No. 564,606.

' one cheek piece below the plane of the pivot e and to the other cheekpiece above the plane of the pivot 6, so that the two jaws shall movetogether but in opposite directions. Upon one of the cheek pieces d, (Z,at each side of the bucket, is pivoted at the extremity of its shorterarm, as at g, the bell crank dumping lever h, the cheek pieces (Z towhich the dumping levers are pivoted being preferably extended upsomewhat farther than the other cheek pieces, as clearly shown inFig. 1. The ends of the long arms of the two levers are connected by ahandle bar 2'. At its angle, as at is, each lever it has pivotallyconnected thereto a link Z, the other end of which is pivotallyconnected to the other cheek piece (Z, also at a point above its pivotalaxis 6.

When the jaws are closed, as shown in Figs. 1 and 2, the pivots g, isand Z, at each side of the bucket, are approximately in line, the pivotk, if out of line preferably standing slightly above the line, so thatthe tendency of the load on the jaws, if slightly unbalanced, to openthe jaws, is resisted by the alinement of the members of the togglesystem formed by the short armh of the lever 72, and the link Z at eachside, the bearing of the handlebar 2' against the end of the bucketpreventing the breaking of the toggle upward in case the pivots g, 70and Z are slightly out of line. lVhen it is desired to open the jaws anddump the load a gentle pull outward on the handle bar 11 serves to breakthe toggles downward and to pull the upper ends of the cheek pieces (Z,(Z, toward each other, forcing the jaws c, c outward in oppositedirections through the link 1". The movement of the jaws to dump theload is thus easily started and is continued by the continued movementof the handle bar 2' without difficulty. To close the jaws, after thedumping of the load, the handle bar 2' is pulled downward and the jawsare thereby restored to their closed positions in which they are lockedagamst accidental movement in the manner already described. In theopening movement of the jaws each jaw swings so closely to the loweredge of the corresponding end wall of the bucket that any material whichmay cling to the upper surface of the jaw is scraped therefrom.

For the protection of the links and their connections, an apron m issecured to each side wall of the bucket, near its upper edge,

and depends downward outside of the links and cheek pieces.

It will be understood that the form and arrangement of the various partsinvolved in the support, locking and operation of the jaws maybe variedto meet difierent conditions of use and that the invention, thereof abucket body, jaws to close the bottom thereof, cheek pieces by which thejaws are pivotally hung upon the walls of the bucket, the pivotal axisof the cheek pieces of each jaw being substantially above the middleline of the corresponding jaw, toggle links connecting the cheek piecesabove their -pivots and serving when in line to hold the jaws in closedposition, and an operating lever connected to the toggle links to breakthe toggle and swing the jaws outward.

3. In a dumping bucket, the combination of a bucket body, jaws to closethe bottom thereof, cheek pieces by which the aws are pivotally hungupon the walls of the bucket, toggle links connecting the cheek piecesabove their pivots and serving when in line to hold the jaws in closedposition, an operating lever connected to the toggle to break the toggleand swing the jaws outward, and a link connecting opposite cheek piecesabove and below their. pivots.

4. In a dumping bucket, the combination of a bucket body, jaws to closethe bottom thereof, cheek pieces by which the jaws are pivotally hungupon the walls of the bucket, a bell crank lever pivotally connected toone of the cheek pieces at the extremity of one arm, and a linkconnecting the angle of the lever with the other cheek piece.

5. In a dumping bucket, the combination of a bucket body, jaws to closethe bottom thereof, cheek pieces by which the jaws are pivotally hungupon the walls of the bucket, a bell crank lever pivotally connected toone of the cheek pieces at the extremity of one arm, a link connectingthe angle of the lever with the other cheek piece, and a link connectingthe opposite cheek pieces above and below their pivots.

6. In a dumping bucket, the combination of a bucket body, jaws to closethe bottom thereof, cheek pieces at each side of the bucket by which thejaws are pivotally hung upon the walls of the bucket, bell crank leverspivoted at the extremities of one arm of each upon the correspondingcheek pieces,

links connecting the angles of the bell crank levers with the oppositecheek pieces and a handle bar connecting the extremities of the otherarm of each of the bell crank levers.

7. In a dumping bucket, the combination of a bucket body, jaws to closethe bottom thereof, cheek pieces at each side of the bucket by which thejaws are pivotally hung upon the walls of the bucket, bell crank leverspivoted at the extremities of one arm of each upon the correspondingcheek pieces, links connecting the angles of the bell crank levers withthe opposite cheek pieces, a handle bar connecting the extremities ofthe other arm of each of the bell crank levers, and links connecting theopposite cheek pieces at each side of the bucket above and below theirpivots.
